预应力水泥混凝土路面具有强度高、接缝少、不易出现病害和设计使用寿命长等优点。为降低造价、连续施工,提出斜张法双向预应力水泥混凝土路面的新概念。通过对斜张法双向预应力水泥混凝土路面关键设计参数的研究,提出了预应力值大小计算方法、斜向无黏结预应力筋的布置方法及U型板的设计方法,并针对试验路进行了初步设计。 Prestressed cement concrete pavement with high strength, less seams, less prone to disease and design advantages such as long life. In order to reduce the cost and make continuous construction, a new concept of diagonal tensioned two-way prestressed cement concrete pavement is put forward. Based on the research on the key design parameters of bias prestressed concrete pavement, the method of calculating the prestress value, the arrangement method of inclined unbonded prestressed tendons and the design method of U-shaped plate are put forward. initial design.
